f75f4194d1 Restructure av_log_missing_feature message 
Some invocations include a verb in the log message, others do not.  Yet
av_log_missing_feature expects callers to provide a verb.  Change the
function to include a verb instead and update the callers accordingly.
The result is a more natural function API and correct English in the
function invocations.

successfully) when trying a new configuration. If the new configuration
fails to decode, restore the last successful configuration.

d53fe096e4 aacdec: Fix out of array writes (stack). 
Set the element to channel vector (e2c_vec) size to be the maximum
number of aac channel elements. This makes it slightly larger than it
needs to be because CCEs are never mapped to output channel locations.

Also add a check that all input tags (legal or not) will fit.

b5fc571e4f latmdec: Check AudioSpecificConfig length before decoding extradata. 
This is different than a normal get_bits() over read because

fd095539d1 latmdec: fix audio specific config parsing 
Pass the correct size in bits to mpeg4audio_get_config and add a flag
to disable parsing of the sync extension when the size is not known.

Latm with AudioMuxVersion 0 does not specify the size of the audio
specific config. Data after the audio specific config can be
misinterpreted as sync extension resulting in random and wrong configs.

bc2dd36740 aacdec: allow output reconfiguration on channel changes 
Locking the decoder against channel config changes in
parse_adts_frame_header() seems to be unnecessary and
streams with channel config changes are reported.

The sample in http://roundup.libav.org/issue999 still works.
